DESTRUCTION NOTICE - Destroy by any method that will prevent disdosure of contents or reconstruction of the document. WARNING. Before starting an inspection, be sure to clear the weapon. Do not squeeze the trigger until the weapon has been cleared. Inspect the chamber to ensure that it is empty and no ammunition is in position to be chambered. Do not keep live ammunition near work area. Use only blank M200 with the BFA and DO NOT fire directly at anyone less than 20 feet away.

3 To be considered SAFE before disassembly, cleaning, inspecting, transporting, or storing, the weapon must be cleared. With the bolt carrier assembly locked to the rear or in its forward position, if the weapon is dropped or jarred with a loaded magazine in place, it could chamber a round. When your weapon is loaded, ensure it is pointed in a safe direction. Do not load with a hot chamber. a WARNING (Cont). If your weapon stops firing with a live round in the chamber of a hot barrel, remove the round fast. However, if you cannot remove it within 10 seconds, remove magazine and wait 15 minutes with the weapon pointing in a safe direction. This way you won't get hurt by possible round cooking off. Regardless, keep your face away from the ejection port while clearing a hot chamber.

4 DON'T OVERHEAT BARRELS. Sustained firing of the weapon will rapidly raise the temperature of the barrel to a critical point Firing 140 rounds, rapidly and continuously, will raise the temperature of the barrel to the COOKOFF POINT. At this temperature, any live round remaining in the chamber for any reason may cook off (detonate). in as short a period as 10 seconds. If the cookoff point (or temperature) is felt possible, weapon should be immediately cleared and allowed to cool. Sustained rate of fire for the weapon is 12-15 rounds per minute. This is the actual rate of fire that a weapon can continue to deliver for an indefinite length of time without serious overheating. b WARNING (Cont). Sustained rate of fire should never be exceeded except under circumstances of extreme urgency.

5 Exceeding the sustained rate of fire can result in a catastrophic failure of the barrel and injury or death to personnel. When disassembling, turn magazine away from face, spring is under compression. If an audible POP' or reduced RECOIL is experienced during firing, immediately CEASE FIRE. Either condition could indicate an incomplete powder bum and/or a bullet stuck in the bore. Do not fire if water is present in barrel. DO NOT interchange bolts between weapons. Be sure the cam pin is installed in the bolt group. If it isn't, your weapon can still fire and will explode. c WARNING (Cont). DO NOT FIRE: Seriously corroded ammunition. Dented cartridges. Cartridges with loose bullets. cartridges exposed to extreme heat (135 ) until they have cooled.

6 Cartridges with the bullet pushed in (short rounds). Make sure your weapon is clear and on SAFE before moving down range. d TECHNICAL MANUAL *TM 9-1005-318-10. NO. 9-1005-319-10 TO 11W35-5-41.
